Shrub rose plant named &#39;baiine&#39;

ABSTRACT

A new and distinct variety of landscape shrub rose plant is provided which abundantly forms on a recurrent basis in clusters attractive double lemon yellow blossoms that mature to pale yellow creating a blend of yellow tints. The blossoms also -display a medium rose fragrance. The plant exhibits a dense upright and bushy growth habit, attractive semi-glossy medium green foliage, and good tolerance to Black Spot and Powdery Mildew. The attractive medium green semi-glossy foliage contrasts nicely with the medium yellow blossom coloration. The new variety is particularly well suited for growing as attractive ornamentation in parks and gardens. The plant is most attractive when planted in groups with other shrubs and perennials.

BOTANICAL COMMERCIAL CLASSIFICATION

Rosa hybrida/Shrub Rose Plant

VARIETAL DENOMINATION

cv. BAIine

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida landscape shrub rose plant was createdat Yamhill, Oreg., U.S.A., during 1996 by artificial pollination whereintwo parents were crossed which previously had been studied in the hopethat they would contribute the desired characteristics. The femaleparent (i.e., the seed parent) was the ‘MACivy’ variety (U.S. Plant Pat.No. 8,362). The ‘MACivy’ variety sometimes is known as the ‘Singin’ inthe Rain’ variety. The male parent (i.e., the pollen parent) was anunreleased shrub rose from my breeding program designated R93412(non-patented in the United States). The parentage of the new varietycan be summarized as follows:

‘MACivy’×‘R93412’

The seeds resulting from the above pollination were sown and plants wereobtained which were physically and biologically different from eachother. Selective study resulted in the identification during 2000 of asingle plant of the new variety having the distinctive ornamentalcharacteristics hereafter described.

It was found that the new variety of the present invention:

(a) exhibits a dense upright and bushy growth habit,

(b) forms on a recurrent basis in clusters attractive double lemonyellow blossoms that mature to pale yellow creating a blend of yellowtints,

(c) forms attractive semi-glossy medium green foliage,

(d) is highly tolerant to Black Spot and Powdery Mildew; and

(e) is particularly well suited for growing as attractive ornamentationin parks and gardens.

The deep yellow buds open to lemon yellow blossoms that age to paleyellow and finally to creamy white. Thereby a blend of yellow tints iscreated.

The new variety well meets the needs of the horticultural industry andcan be grown to advantage in the landscape where attractiveornamentation is desired. The plant is most attractive when planted ingroups with other shrubs and perennials. The medium yellow blossomscontrast nicely with the semi-glossy medium green foliage. An attractivetough new shrub rose that can be grown in U.S.D.A. Hardiness Zone Nos. 4to 9 is provided.

The new variety can be readily distinguished from other varietiesincluding its ancestors. For instance, the ‘MACivy’ variety is aFloribunda that forms apricot/copper blooms having approximately 25 to30 petals, bears medium green to dark green glossy foliage, and displaysa sweet musk fragrance. R93412 is a shrub rose that forms light yellowblossoms of approximately 15 petals having a diameter of approximately 8cm, and forms glossy dark green foliage with red new growth.

Also, the new variety readily can be distinguished from the ‘J. P.Connell’ (non-patented in the United States) and ‘MORyelrug’(non-patented in the United States) varieties. More specifically, the‘J. P. Connell’ variety exhibits a generally taller growth habit andforms considerably larger blossoms having a lesser number of petals, andthe ‘MORyelrug’ variety is a hybrid Rugosa that also forms considerablylarger blossoms having a lesser number of petals.

The new variety beginning in August 1997 has been found to undergoasexual propagation by budding on an understock and by the rooting ofcuttings. ‘Dr. Huey’ rootstock was used during the budding. Such asexualpropagation by these techniques at Yamhill, Oreg., U.S.A., St. Paul,Minn., U.S.A., and at Phoenix, Ariz., U.S.A. has shown that thecharacteristics of the new variety are stable and are strictlytransmissible by such asexual propagation from one generation toanother. Accordingly, the new variety reproduces true to type. The newvariety grows well on its own roots.

Initially the new plant was designated 96R683. The new plant has beennamed the ‘BAIine’ variety, and currently is being marketed while usingthe GARDEN ART, EASY ELEGANCE, and YELLOW SUBMARINE trademarks.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonablypossible to make the same in color illustrations of this character,typical specimens of the new variety. The rose plants of the new varietyhad been propagated by the rooting of cuttings, were approximately twoand three years of age, and were being grown outdoors during the 2003and 2004 seasons at St. Paul, Minn., U.S.A., and at Yamhill, Oreg.,U.S.A.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). Common color terms are tobe accorded their ordinary dictionary significance. The description isbased on the observation of two, and four year-old plants while grownoutdoors on their own roots during June 2003, at Yamhill Oreg., U.S.A.,and during July 2004 at St. Paul, Minn., U.S.A.
